This paper proposes a low-cost design for a two-axis CNC laser engraving machine that provides similar functionality to high-cost industrial systems. The proposed design is suitable for university laboratories due to its accessibility, small size, ease of use, low manufacturing cost, and transportability. The machine is based on an Arduino platform and uses a high-watt burning laser module to engrave 2D and grayscale images on paper, plastic, and wood. The dimensional, dependency, and coordinate tests were conducted to verify the validity of the machine. Finally, pilot experimentation was carried out on cardboard composites, plastic, and wood.
